Question

If the radius of the circle is 7 cm then its circumference is

Answer 1

C = 2 × pi × r

= 2 × 22/7 × 7

= 44

Answer 2

As we know that the data given below is provided in the question,

In the above question, it is given that,

Given that the radius of the circle is 7 cm.

Here we have to find the circumference of a circle.

We have to use the formula of the circumference of a circle.

Thus, circumference is $=2\pi r$

Substituting the value in the above equation we get,

$C=2\times \pi \times 7\\C=43.98cm$

Hence the circumference of a circle is 43.98cm.
